Ultraman Leo

Voiced by: Ryu Manatsu
A Ultra warrior hailing from the planet L77 (whereas all other Ultras are from M78), Ultraman Leo's homeworld was destroyed by the Alien Magma and twin kaiju called the Gilas Brothers, so he came to Earth in the guise of a human named Gen Ohtori and trained under Ultraseven, becoming a skilled martial artist more reliant on his physical capabilities than most Ultra heroes. Ultraman Leo has also reappeared in other series, and most notably, is the mentor of Ultraseven's own son Ultraman Zero.
  • Animal Motifs: Lions. His theme song has the verse "The eye of the lion is shining" and a lion's head is used to symbolize L77.
  • Bare-Fisted Monk: The Ultraman equivalent of one, as Leo relies almost entirely on unarmed melee combat as opposed to flashier beam attacks used by most other Ultra heroes.
  • Big Brother Instinct: So much that he was willing to fight the Ultra Brothers to defend Astra when the latter was accused of stealing the Ultra Key from the Land of Light (which turned out to be Alien Babalou in disguise).
  • Diving Kick: His signature Finishing Move is the Leo Kick, created as a friendly nod towards Kamen Rider.
  • Elemental Punch: Variant. Leo is able to encase his karate chops in fiery energy for some truly devastating attacks that usually end with a monster get a body part lopped off.
  • Fighting with Chucks: When he does use weapons, it's usually this. He even once turned a pair of factory smokestacks into one to battle the murderous Alien Kettle.
  • Hand Blast: While Leo is better known for his usage of his own bare hands, he does get a few minor ones later on in the series.
  • Horned Humanoid: One of the few Ultramen with horns.
  • Meaningful Name: Name after the constellation of Leo, the lion, in which L77 is located in.
  • Panthera Awesome: As stated above, lions form his major motif.
  • Spin Attack: Able to perform spinning kick attacks powerful enough to knock the heads of his opponents' bodies.
  • Super Strength: Even by the standards of the Ultramen, Leo's physical power is unmatched, thanks to years of Training from Hell.
  • Swiss Army Weapon: The Ultra Mantle, which he carries on his left arm in the form of a bracelet. A gift from Ultraman King originally used to defeat the alien wizard Pressure.
  • Training from Hell: Put through all sorts of it to become the skilled martial artist he is today.
  • Warrior Prince: He was a prince back on his homeworld.


Voiced by: Ryu Manatsu (stock grunts), Chikara Osaka (Ultra Fight Victory onwards)
Ultraman Leo's younger twin brother, who was initially presumed dead after the destruction of L77, but reappears to assist Leo against the monster brothers Gallon and Litre. He returns to assist Leo many more times in the series and often appears alongside Leo in other series too.
  • Combination Attack: He and Leo often perform these, with the most notable being the Ultra Double Flasher, a beam of red lightning fired with Leo standing behind a kneeling Astra.
  • Dark and Troubled Past : He barely survived the destruction of L77, and was captured and imprisoned by the Alien Magma, who tortured and enslaved him. It was only the intervention of Ultraman King that got him out of it, and only from King did he learn that his brother had survived.
  • Deus ex Machina: His role in Ultraman Leo. He'd always appears suddenly during a battle to help Leo against whatever the monster was giving his older brother trouble, like Gallon and Litre, Alien Akumania, Alien Atlanta, and Hangler.
  • Diving Kick: Has his own version of the Leo Kick called the Astra Kick.
  • Hand Blast: He uses beam attacks a lot more than Leo does.
  • Meaningful Name: His name is Latin for "star".
  • The Quiet One: He never said anything in the entire series, only gaining his first speaking role some 40 years later.
  • Sibling Team: While they only occasionally worked together in the series, later Ultra Series almoost always have Astra and Leo together, like in Ultra Fight Victory and Mega Monster Battle: Ultra Galaxy Legends.
  • Slave Collar: Variant. He wears one around his left leg — the only external remnant of the time he spent as a slave of the Alien Magma.
  • Twin Desynch: As a result of his time spent as a prisoner of the Alien Magma, Astra has become fairly different from Leo. Notably, Astra used to have horns, but they were sawed off by the Alien Magma.

Ultraman King

Voiced by: Motomu Kiyokawa (Ultraman Leo and Ultraman Mebius), Junichiro Koizumi (Mega Monster Battle: Ultra Galaxy Legends), Nobuyuki Hiyama (Ultraman Geed), Masao Nakasone (stock grunts, since Ultraman Zero: The Chronicle)
The most powerful Ultraman in existence and a virtual god amongst the Ultras, Ultraman King is a reclusive and mysterious hermit who hides on a distant world. He only appears in times of serious crisis when all seems completely lost against forces of evil.
  • Badass Beard: One of the few Ultras to sport facial hair.
  • Badass Cape: His Ultra Mantle, which can transform into anything he wishes and can even deflect attacks. He gave it to Leo for the series, but got it back afterwards.
  • Big Good: of the entire Ultra Series, although since he's a hermit, the Father of Ultra tends to fill in the more active needs of the role.
  • Deus ex Machina: His role in Ultraman Leo is to make sure the day can be saved whenever things seem totally hopeless. He does against Alien Pressure (when Leo is shrunken down by the wizard), Alien Babalou (revealing him to be disguised as Astra to end the conflict between the Leo Brothers and Ultra Brothers), and Alien Bunyo (when Bunyo and Commander Black chop Leo into pieces).
  • Godzilla Threshold: He only gets involved in the Ultra warriors' battles if there is no other way for whatever crisis they are facing to be solved, such as the Land of Light about to collide with Earth while the Ultra and Leo Brothers are engaged in in-fighting or Ultraman Belial successfully activating a weapon capable of destroying the universe.
  • Hermit Guru: Usually lives as one, spending his time meditating and observing the Space Garrison from an isolated planet. In fact, no Ultra had ever seen King until Leo's battle against Alien Pressure forced him to make an appearance.
  • I Have Many Names: He tells this to Ultraman Hikari in the Hikari Saga gaiden, saying that "Ultraman King" is simply what humans have given him.
  • Mysterious Past: It's known that the Ultras developed their powers from the Plasma Spark, but Ultraman King was already an Ultra long before that and his origin is unknown. Only Ultraman Nexus is more ancient than him.
  • Non-Indicative Name: Despite his given title of "king", Ultraman King isn't actually the ruler of the Land of Light. It just befits his incredible power.
  • Non-Standard Character Design: He's the only good Ultra with red eyes.
  • The Omnipotent: His powers are virtually infinite and he's regarded as all powerful, and more than backs up that claim. He's capable of effortlessly bring back a dismembered Leo to life and curbstomped the immensely powerful Ultraman Belial, then created the Land of Light's moon around him to seal him away. In Ultraman Geed, he recreates the freaking universe.
  • Physical God: When a species of immensely strong, 50 meter tall energy beings considers you their deity, you have to be this.
  • Time Abyss: He predates the Land of Light and is at LEAST 300,000 years old, probably older. To note, the Father of Ultra is considered old by his people's standards at 160,000.

    Monsters and Aliens 

Alien Magma

First Appearance: The Death of Seven! Tokyo Sinks!
One of the brutal race that destroyed Ultraman Leo's homeworld at the beginning of the series, Alien Magma set his eyes on Earth with his monster lackeys, the Gilas Brothers, to devastate cities with the monsters' tsunami-creating powers and defeat Ultraseven. He would return in Episode 28 when he attempted to marry the bird-like alien Rolan, coming face-to-face with Ultraman Leo once more.

Alien Magma has appeared several more times in the Ultra Series, due to being one of Ultraman Leo's most popular and iconic enemies. The hairstyle, eye colour, and weaponry have also changed a number of times over the course of the franchise.

  • Hand Blast: Can fire a variety of energy bolts from his hands, including a blue laser and finger bolts.
  • Knight of Cerebus: Alien Magma shows off right from the start that Ultraman Leo is nothing like the wacky Ultraman Taro by defeating Ultraseven and successfully sinking an island-city with the help of the Gilas Brothers.
  • Shapeshifter Weapon: His hands are able to transform at will into a lance-like sword called a Pata for combat. In later incarnations, he can also transform them into a hook.

    • Hook Hand: Typically his left hand, which can also be launched out with a grappling chain.
  • Villain Decay: In his reappearance. He's gone from sinking an island, flooding Tokyo, crippling Ultraseven, and destroying Leo's homeworld, to harassing children for their toy fans and trying to marry some bird alien.
  • Villain: Exit, Stage Left: He runs away after the Gilas Brothers are killed and vanishes until Rolan's appearance, where he's finally offed for good.
  • The Worf Effect: He and the Gilas Brothers defeat Ultraseven at the start of the series, showing exactly the direction of the series, as well as Magma's ruthlessness.

Gilas Brothers

First Appearance: The Death of Seven! Tokyo Sinks!
Alien Magma's twin monster lackeys, who specialize in creating devastating floods and using tag team abilities, which Gen had to train against. They also successfully crippled Ultraseven at the start of the series.
  • Attack Reflector: Both brothers can lock hands together and spin themselves rapidly to reflect all attacks against them.
  • Combination Attack: All the Gilas Brothers' powers are based around this, particularly their Spin Attack, which allows them to spam their laser bolts and create a powerful electrified force field. Gen had to train against these powers too.

  • The Dragon: Both of them are Alien Magma's loyal monster minions and do most of the dirty work for him.
  • Everything's Better with Dinosaurs: They certainly resemble the part.

Alien Tsuruk

First Appearance: Farewell to Tears
A ruthless swordsman from outer space who murders Tooru and Kaoru's father, bringing them under the care of Gen and Momoko. Gen had to train against the alien's deadly wrist blades that grant him his lethal swordsmanship skills.

  • Master Swordsman: A murderous blademaster whose swiftness and brutality with his wrist blades were so great that Gen had to go through his usual Training from Hell in order to counter them.
  • One-Winged Angel: Tsuruk transforms himself into a giant reptilian monster instead of merely increasing his size, which is how he battles Ultraman Leo. He maintains his lethal wrist blades in this form.


First Appearance: Don't Cry! You're A Man!
An extraterrestrial monster with the ability to hurl its horn like a boomerang. Naturally, Gen had to train hard in order to find a way to counter Kanedoras' skills with its boomerang horn.

Alien Karly

First Appearance: Burn On! You're A Man!
A murderous alien with massive shoulder spikes which he uses to successfully kill several members of MAC. It was exactly for this reason that Gen needed to train himself to overcome the alien's weapons.
  • Impaled with Extreme Prejudice: His fate, as Ultraman Leo manages to rip off one of his shoulder spikes and stab him in the skull with it.
  • One-Winged Angel: Like Tsuruk, Karly transforms himself into a giant reptilian monster rather than increasing his size. He uses this ability to battle Ultraman Leo, and still has his deadly shoulder spikes.
  • Shock and Awe: Shoots lightning from his shoulder spikes and can electrocute enemies who try to grab them.
  • Spikes of Doom: He relies on the two huge spikes on his shoulders to overwhelm his opponents. Naturally, Gen had to train himself to counter the weapons.


First Appearance: A Beautiful Man's Disposition
A strange alien monster that spawned a dangerous flower which Kaoru took care of. It used the flower to gain the ability to hurl shuriken-like petals from its body, which was what Gen needed to train himself against for the episode.
  • Battle Boomerang: The shuriken petals act as these, and Gen had to train against them.
  • Foul Flower: Kendoros gains its shuriken petals from the alien flower growing on the top of its body, but it has to create the flower and let it grow in order to gain the ability.
  • Hand Blast: Is able to fire bullet-like energy missiles from its fingertips.
  • Helicritter: The flower on it top acts as a propeller for flight.

  • Rolling Attack: Kendoros can retract its body parts into its bulb-like body to roll about and over enemies.


First Appearance: Certain Kill! Monster Challenger!
A monster whose Achilles' Heel is its back and is smart enough to make sure that its enemies will never be able hit it from behind. Gen had to train himself to find a way to be able to get behind Vekira and strike its weak spot.
  • Achilles' Heel: Vekira's backside is so vulnerable to attack that it will die if hit from behind hard enough. However, the monster knows this and always ensures that its back is never facing the enemy, so Gen had to train in order to somehow hit the monster from behind.
  • Breath Weapon: Can breath a shower of explosive sparks.
  • Everything's Better with Dinosaurs: Resembles one, but its origins are never stated.

Alien Giro

First Appearance: The Bridge of Friendship that Spans the Universe
A friendly alien who came to Earth to enjoy its sights, befriending Tooru along the way. Unfortunately, his friendship with the boy was met with suspicion by MAC, and Dan forced Gen to train against the alien's ability to create hindering foam from its antennae.
  • Achilles' Heel: His antennae are not only the source of his most potent powers, but he will actually die if they're torn off.
  • Aliens Among Us: Giro can't disguise himself as a human like many Ultra aliens, so he hides by blending in with the monster statues at an amusement park.
  • Amusing Alien: He was merely a friendly and fun-loving alien who just came to Earth to make friends and travel as a tourist. Unfortunately, MAC's suspicion of potential alien invaders led to him fighting Ultraman Leo.
  • Little Green Men: He strongly resembles one.
  • Spell My Name with an "S": Sometimes spelled as Guiro.
  • Sticky Situation: Giro's primary power (and that which Gen had to train against) is to spray a white foam from his antennae that solidifies upon contact with solid matter, slowing and hindering his enemies in sticky white foam.

  • Breath Weapon: Breathes fire.
  • Came from the Sky: Arrives on Earth in the form of a comet.

  • Eye Beams: Can shoot lasers from his eyes.
  • Magma Man: Ron consumes lava, which was how he turned from a small animal into a gigantic monster.
  • Make My Monster Grow: Ron is normally only about the equivalent of a small dog in terms of comparing his size to that of Ultraman Leo, but its grief and rage, as well as a steady diet of magma, made it the size of Ultraman Leo.

  • Prehensile Tail: Uses his tail to constrict Ultraman Leo during their fight.
  • Playing with Fire: Asides from his Breath Weapon, he can also shoot fire from his tail.

  • Woobie, Destroyer of Worlds: Ron was only rampaging because he had been driven to madness by the grief over being separated from Ultraman Leo. Even Gen feels deeply sorry for Ron and refuses to battle him as he rampages.

Alien Kettle

First Appearance: One Man Covered in Mud
A vicious alien thug who kills the uncle and aunt of Ichiro Matsumoto, one of the boys at Gen's sports facility. The shame of failing to save the kid's family and his inability to overcome the alien's superhuman strength and speed led Gen to once again go through Training from Hell.
  • Badass Normal: Despite having no powers beyond the stock one of changing his size, Kettle was so strong and agile that Gen had to merely train against the alien's superhuman martial arts skills instead of some special ability he had.

Alien Vibe

First Appearance: Huge Explosion! Two Aliens in Crisis!
A bloodthirsty alien invader with the ability to vibrate his body at such speeds that he is rendered invisible. Naturally, Gen had to figure out how to train against an enemy that he could not see.

  • Invisibility: Which he performs by moving his entire body at Super Speed.
  • Punny Name: So called for his vibrating abilities, which is what allows him to turn invisible and move at superspeed.

First Appearance: Certain Kill-Fists! A Young Boy Calls Up a Tempest!
Played by: Kawashiro Famiyoshi (human form actor)
A scorpion-like monster able to shapeshift into a young and hotheaded human martial artist with a secret invisible stinger technique. The agonizing pain of the invisible stinger was exactly what Gen had to train against for the episode.
  • Beware My Stinger Tail: Being a scorpion kaiju, Antales uses his claw-like stinger tail in combat. In his human form, the tail is invisible allowing him to still use it. It was also the ability Gen had to train against.

An evil alien with the ability to create illusory duplicates of himself. Gen, of course, had to train against this confusion-inducing technique by seeking the help of a blind martial artist.
  • Doppelgänger Spin: Creates illusions of himself to battle Ultraman Leo. Gen had to train to figure out how to distinguish the real one. The trick is that the real one is the only one whose footsteps can be heard.

  • Expy: Of Alien Baltan from the original Ultraman, who has almost the exact same Doppelgänger Spin ability and Evil Laugh.

Alien Atler

  • Foul Flower: Carries the Black Orchid on her chest, which allow her to change shape. It also shoots a ray of energy that turns victims into silver, but in the battle with Ultraman Leo, it only has a minimal effect due to their larger sizes.
  • Taken for Granite: Her Black Orchid encases people in silver, turning them into statues or simply welding their legs.
  • Voluntary Shapeshifting: Takes on the form of a ghost-like lady in white to lure men and kill them with her Black Orchid.

  • Demonic Possession: His method of turning people into "werewolves". If the person has any special traits (eg: Saeko and her gymnastic skills), he gains those in his monstrous form.
  • Our Werewolves Are Different: Very different. First of all, he's an alien. Secondly, and more interestingly, he actually turns people into werewolves by possessing them instead of biting them, forcing them to transform into Alien Wolf at night. Also, he has a number of vampire traits, notably drinking blood for sustenance and having a habit of specifically targeting women.
  • Spin Attack: Due to the fact that he was possessing the body of Saeko the gymnast, Alien Wolf inherits the girl's spinning acrobatics and uses it to perform a pinwheel attack.
  • Spring Jump: Not actually taken from Saeko, but rather a standard ability for Alien Wolf.
  • The Tooth Hurts: Ultraman Leo tears out Alien Wolf's fangs during the fight.


First Appearance: Vampire! The Bat Girl!
Voiced by: Tomoko Sakamoto (also human form actor)

  • Blow You Away: Like all winged monsters, she is able to create powerful gusts by flapping her wings. To solve this, Leo simply just rips her wings apart.

Alien Boze

First Appearance: Revival of the Half-Man Fish
A fish-like alien who has been terrorizing a fishing village in Hokkaido for a century. It happened to be that Gen, Momoko, and the kids were vacationing in that exact village, soon bringing the fearful villagers' story of a sea monster to the attention of MAC.

  • Human Aliens: Appears as one, although it's more likely that we never actually see his true form.
  • Meaningful Name: Bock's name comes from "Koro-pok-guru", the name of a race of gnome-like people in the folklore of the Ainu people who inhabit Hokkaido.
  • Ursine Aliens: Implied. We never see his true form, but considering Dogyuh, it's likely he resembles one.

Alien Coro

First Appearance: The Mischievous Alien Who Fell From His Bed
Played by: Yasuhiro Masuda (actor), Kazue Takahashi (voice)
A child-like alien who spends most of his time resting on a spacefaring bed, but one day, he fell out and landed on Earth, where he befriended Tooru and Kaoru. However, he ends up causing a lot of trouble, especially when he summons his pet monster Renbolar to show off to the kids.
  • Amusing Alien: Coro is purely a goofy, fun-loving alien who has no ill intentions (as appropriate for a Breather Episode). He causes a lot of trouble through his mischief with Tooru and Kaoru though, not to mention the whole Renbolar fiasco.
  • Big Eater: He eats a lot when Tooru and his friends get him several boxes of donuts. However, he gets a stomachache from it.
  • Kid with the Leash: Coro controls Renbolar entirely through his tail, so if it gets torn off, Renbolar will rampage. Fortunately, if that happens Coro can regrow his tail, which is sped up by standing on his head.
  • Really 700 Years Old: Despite his child-like appearance and personality, he says he's old enough to be a great-grandfather!
  • Rubber-Forehead Aliens: The only physical differences between him and a human boy are that Coro has big floppy ears and a tail.
  • Trademark Favorite Food: He got hungry upon arriving on Earth, Tooru and his friends got him some donuts, and he enjoyed them so much that he and Renbolar bring some back home.


First Appearance: The Mischievous Alien Who Fell From His Bed
Coro's pet monster, which he controls through his tail. Unfortunately, when of Tooru's friends pulls on Coro's tail too hard, yanking it off, Renbolar goes berserk!
  • Beware the Silly Ones: Despite his goofy personality, Renbolar proved to be an extremely powerful enemy. Thankfully, Coro regrew his tail quickly enough to keep Renbolar from defeating Leo.
  • Everything's Better with Rainbows: Can consume rainbows to increase his strength.
  • Fighting Clown: Renbolar's battles with Leo are highly comedic, with their first fight playing out quite similarly to a very goofy boxing match.
  • Non-Malicious Monster: As another Breather Episode monster, Renbolar is a purely peaceful creature, so long as Coro can keep him under control. But even when it goes berserk, Renbolar is still pretty ineffectual.
  • Pet Monstrosity: Of Alien Coro, who controls the monster via his tail.
  • Punny Name: Renbolar's Japanese name "Renbora" is derived from the Japanese pronunciation of "rainbow".
  • Why Did It Have to Be Snakes?: Renbolar is afraid of water, and when a rainstorm hits Tokyo, the monster runs away.

Alien Sarin Carolyn

First Appearance: The Beautiful Maiden from Virgo
Played by: Mariko Matsuoka
Professor Dodole's granddaughter who flees with her father to Earth to escape a robot rebellion on their homeworld. A romance begins to flourish between her and Gen on Earth, but when Gamelot arrives, it turns out Carolyn is not what she seems.
  • Heroic Sacrifice:In order to help Leo kill Gamelot, Carolyn self-destructs to blow a hole in Gamelot's armour.
  • Human Aliens: Or so it seems...
  • Mad Scientist's Beautiful Daughter: Granddaughter technically, but who's keeping track? Dodole can't really be called "mad", but he did build the robots that destroyed his homeworld. Carolyn was also beautiful enough that Gen developed feelings for her.
  • Robotic Reveal: Turns out to be an android, and she self-destructs in order to damage Gamelot enough for Leo to kill him.


First Appearance: The Beautiful Maiden from Virgo
The vanguard of the robot revolution in Virgo that killed off Professor Dodole and Carolyn's species, Gamelot was sent to Earth by the other robots of Virgo in search of the survivors.

  • Transforming Mecha: Can retract his head and limbs inside his body to fly.

Alien Clean

Alien Clean tells him that he cane come to his world, which has no filth or pollution and is where Jiro's disappeared pet tortoise and rhinoceros beetle are supposedly living.
  • Human Aliens: It's implied Alien Clean doesn't actually exist and was just part of Jiro's dream, thus no actual connection to Satan Beetle. However, the episode is kinda confusing on the whole, so it's completely possible there really was an Alien Clean fooling him through dreams and had actually sent Satan Beetle to Earth to destroy humanity.

Satan Beetle

First Appearance: The Rhinoceros Beetle is a Space Invader!
An extraterrestrial insect-like monster that unexpectedly arrives to Earth. It was believed by a boy anmed Jiro to be his lost pet rhinoceros beetle sent as an ambassador by Alien Clean.

  • Breath Weapon: King Paradai breathes choking black smoke.
  • Fish People: Their episode is inspired by the folktale of Urashima Taro, the boy who visited the bottom of the sea and the palace of Ryujin, the Japanese dragon god of the sea. However, they live in a submarine rather than swimming about in the ocean.
  • Fusion Dance: Two Paradai are able to transform themselves into King Paradai by merging together.
  • Horn Attack: King Paradai can shoot energy bolts from its horns.
  • Mind over Matter: The Paradai have telekinetic powers.

Ultraman Leo does not take kindly to this.
  • Prehensile Tail: King Paradai uses its tail to strangle Ultraman Leo in their fight.
  • Rolling Attack: King Paradai is able to curl itself into a ball to deflect attack of its hide while ramming into enemies.

Alien Uringa

First Appearance: Reunion of Fate! Dan and Anne!
Played by: Keiji Shimizu (human form actor)

  • Eye Beams: Able to fire a series of telekinetic rings from his visor.

  • Shock and Awe: Can fire green lightning from the horns on his helmet.
  • Spike Shooter: Can fire the spikes from his armour as missiles, or even use them as daggers in melee combat.


First Appearance: The Monster's Favour
Played by: Hiroko Sakurai (human form actress)
A bird-like alien described as the most beautiful creature in the universe, which attracted the attention of Alien Magma, who sought to marry her. She manages to escape with Ultraman Leo's help, but is injured until a bike shop owner and his son help her, so in gratitude she takes on a human form to work at their bicycle shop and give toy pinwheels to children.
  • Bird People: She's an intelligent bird-like alien described as the most beautiful being in the universe. It's also worth noting she was inspired by a classic Japanese fairy tale Tsuru no Ongaeshi (usually called The Grateful Crane in English).
  • Friend to All Children: She shows signs of this, as she presents children with toy pinwheel fans she made
  • Informed Attribute: Admittedly, her true form is not as beautiful as the show says, but that's what happens when you recycle the costume from Alien Northsatan mixed with Alien Wolf.

Alien Virmin

First Appearance: The White Flower that Protects Earth
Voiced by: Nobotu Nakaya (also human form actor)

  • Green Thumb: He can create poisonous flowers that put humans to sleep. Additionally, his antennae can fire a laser that creates entangling vines around his enemies, as well as fire a mist from his hands that makes his poisonous flowers grow on whatever they hit.
  • Insectoid Aliens: Sorta looks like a giant cockroach.
  • Punny Name: On "vermin", since he's an insect-like alien.
  • Spell My Name with an "S": Virmin or Vermin? It all depends on ow literally you translate his name.

A monster from the Moon who comes to Earth to pick up a young lady named Kaguya who does not realize she's actually the princess of the Moon. However, Kaguya is reluctant to part with her Earth family, and even Gen doesn't believe Kirara should take the princess back home.

Alien Akumania

First Appearance: Leo Brothers vs. the Space Demon
Voiced by: Eiji Maruyama
A demon-like alien who arrives on Earth in the form of a giant floating eyeball, causing all sorts of disturbing supernatural happenings around an apartment ground with his mere presence. Alien Akumania has become a bit of an Ensemble Dark Horse since then, earning it a few reappearances like in Ultraman Ginga S.
  • Breakout Villain: Not to the extent of Alien Magma and Alien Babalou, or Nova, but Akumania has proven to be decently popular enough to earn some reappearances.
  • Casting a Shadow: Can cloak a targeted area in darkness.
  • Cephalothorax: His eye and mouth are located on his chest and belly.
  • Cyclops: Has a single eye.
  • Eye Beams: In eyeball form, he can fire energy blasts, as well as a ray of energy that causes spectral hands to appear out of the ground and grab victims.
  • Eye Scream: Gets his eye punctured during his battle against Leo and Astra when they toss one of his horns into it.
  • Faceless Eye: Can transform himself into one for flight.
  • Mind over Matter: Has telekinetic powers. In fact, when Leo tears off his arms in the fight, Akumania uses his telekinesis to guide his severed arms to strangle Leo and reattach them to his body.
  • Our Demons Are Different: His name is derived from the Japanese word for "demon" and he also has several demonic powers, but really he's just an extraterrestrial.
  • Starfish Aliens: Easily one of the weirdest alien designs in this series.


First Appearance: Ultra Brothers, Eternal Vows
A two-faced demon-like monster that attacked Ultraman Jack while he was on his way to give Sevengar to Dan and take the Ultra Eye back to M78. Ashuran uses its powers to create a muzzle around Jack that remains when he becomes Hideki Goh, preventing Jack from speaking.
  • Breath Weapon: Breathes fire from both faces.
  • Eye Beams: Fires bolts of energy from both of his faces, but can also shoot out a beam that encases its victim's mouth in a near-indestructible iron mask, which he used to prevent Goh from being able to say anything to Dan and Gen.
  • Meaningful Name: Ashuran's name is derived from "Asura", a class of demons in Indian mythology that are sometimes portrayed with multiple faces.
  • Oni: Although he's mainly based on the Indian Asuras, Ashuran also takes heavy inspiration from Oni as evidenced by his red-and-blue design.
  • Two-Faced: One side of Ashuran is red and the other is blue, but otherwise they're totally identical.


First Appearance: Ultra Brothers, Eternal Vows
A robotic Capsule Monster that Ultraman Jack intended to give to Dan as something to assist Ultraman Leo while Jack took the Ultra Eye back to the Land of Light for repairs.
  • Awesome, but Impractical: Although Sevengar managed to pummel Ashuran with ease when released, his 50 hour recharge time and one minute time limit meant he ultimately did very little against the demon-like kaiju. This is the likely reason why he's never used again afterwards.
  • Hand Blast: Fires missiles from his fingertips.
  • Hour of Power: Unlike Seven's Capsule Monsters (but similar to the Maquette Monsters of Ultraman Mebius), Sevengar can only last for one minute before returning to his capsule. Afterwards, the capsule cannot be used for the next 50 hours as he recharges.
  • Humongous Mecha: A giant robot that the Ultras had specifically created for usage as a Capsule Monster.
  • Mons: He's a Capsule Monster like Miclas, Windam, and Agira, and even has a "Monster Ball" (beating Pokemon by about 20 years!).
  • Sealed Good in a Can: He's stored inside in a football-shaped object called a Monster Ball, which looks very different from the capsules used by Dan in Ultraseven.
  • Super Strength: Which is what makes Sevengar is the most powerful of all the Capsule Monsters, allowing him to overpower Ashuran with no problems.
  • Tin-Can Robot: Sevengar has a very canister-shaped body.


First Appearance: I'm the Monster General
Voiced by: Fuyumi Shiraishi
A mischievous alien child sealed inside a jar by his parents for his misbehavior and poor grades in school. He eventually arrives on Earth, where befriends a boy with an equally poor performance at school named Miyasaka, "the Monster General", and causes a lot of trouble.
  • Amusing Alien: He's another Breather Episode monster, so this is a given. The worst he really does is destroy an empty school building when he turns giant-sized, but the kids don't seem to mind.
  • Attack Reflector: The warts on his body are able to reflect projectile attacks.
  • Bilingual Bonus: His name means "'General" in Japanese, which reflects his friendship with a kid nicknamed "the Monster General". Taishoh's the literal monster general.
  • Bratty Half-Pint: The reason why his parents have sealed him inside a magical pot was due to his extremely bad behaviour and performance at school. When he arrives on Earth, he causes just as much havoc for the kids and MAC.
  • Cool and Unusual Punishment: Taishoh was placed inside a magical pot and thrown into space for how much of a brat he was, but Miyasaka released him when he arrived on Earth. Ultraman Leo seals him back up again for all the trouble he causes.
  • Fighting Clown: His battle with Ultraman Leo is very much a slapstick-type fight, befitting of Taishoh's mischievous behaviour.
  • Potty Failure: Suffers from this when Miyasaka brings him inside the jar to school, only for taishoh to have to really use the bathroom. It turns out the jar has a leak too, much to Miyasaka's embarrassment!

Alien Atlanta

First Appearance: Fly, Leo Brothers! Save the Space Base!
Played by: Tetsuo Nogawa (human form actor)
A sinister alien who takes the form of an astronaut named Uchida who, unbeknownst to everyone but Gen and Dan, was killed when he landed on Atlanta's homeworld. He joined MAC in his human disguise, intending to plant a bomb in the MAC base to assassinate Uchida's fiance's father — the supreme commande rof MAC.
  • Badass Normal: Despite not really having any unique combat powers beyond the usual size-increasing one, he gave Ultraman Leo a tough enough time that Astra had to show up and help him out.
  • Bitch in Sheep's Clothing: Gen and Dan know all too well that Uchida is in fact Alien Atlanta coming to Earth with murderous intentions, but because Uchida is highly regarded by the rest of MAC and is supposed to marry the daughter of MAC's top leader, they can do pretty much nothing to stop him.
  • Dead Person Impersonation: Takes on the form of Uchida, whom he killed, in order to join MAC and destroy them.

Alien Mazaras

First Appearance: Mystery! The Devil in the Mirror!
Voiced by: Chisako Hara (also human form actress)
An alien who resides in the mirror world, stepping out to capture Kaoru to replace her own lost daughter by impersonating the girl's deceased mother while she sending out her monster Specter to ravage the real world.
  • Blade on a Stick: Her weapon of choice is a yari, a weapon historically used by samurai that resembles a sword mixed with a spear.
  • Dead Person Impersonation: Takes on the form of Tooru and Kaoru's mother to capture Kaoru. Kaoru sees through the disguise when she sees her brother being harmed by Specter's rampage and realizes her mother would have also tried to save Tooru in such a situation.
  • Master of Illusion: Asides from taking the form of Tooru and Kaoru's dead mother, she also creates various hallucinations to confuse Ultraman Leo in their fight.
  • Mirror Monster: Unlike most seijins, Mazaras isn't the name of her homeworld. She lives in the mirror realm instead.
  • Oni: Essentially an Oni mixed with Bloody Mary, in terms of appearance and behaviour.
  • Tragic Villain: Mazaras kidnapped Kaoru to replace her deceased daughter, so even Ultraman Leo felt bad for her when they fought.


First Appearance: Mystery! The Devil in the Mirror!
Alien Mazaras' monster minion, who she sends into the real world to ravage Tokyo while she battles Ultraman Leo and holds Kaoru hostage in the mirror world.
  • Attack Reflector: Its mirror-like body can reflect weak attacks, such as the gunfire from MAC.
  • The Dragon: Of Alien Mazaras.
  • Literally Shattered Lives: Specter shatters into hundreds of mirror shards when Ultraman Leo kills it.
  • Mirror Monster: Not only does Specter hail from the same realm as its master Mazaras, but it is also completely made out of mirrors!
  • Poisonous Person: Is able to shoot toxic gas from its hands.
  • Power Crystal: Specter has several on its head that are able to shoot out weak energy beams.

Alien Babalou

First Appearance: Battle! Leo Brothers vs. Ultra Brothers!
Voiced by: Motomu Kiyokawa
One of the most wicked aliens in the universe, Alien Babalou transformed himself into the likeness of Astra to steal the Ultra Key, the device that keeps the Land of Light in orbit, before coming to Earth. The result was that Ultraman, Zoffy, Ultraman Jack, and Ultraman Ace branded Astra a traitor, which led to a vicious battle between the Leo Brothers and the Ultra Brothers while the Ultra homeworld was sent on a collision course with Earth.

Among Ultraman Leo's most iconic and dangerous enemies, Alien Babalou has reappeared many times in other entries of the Ultra Series, where he remains a cunning and powerful foe who continues to use his shapeshifting abilities to sow havoc and distrust among humans and Ultras alike.

  • Arm Cannon: His left arm's bracer is equipped with a small one capable of launching small purple lasers.
  • Blade Below the Shoulder: He possesses a small switchblade on his right arm's bracer.
  • Blade on a Stick: His favored weapon is a polearm with a spiked mace on the end called a Ji.
  • Breakout Villain: Babalou is probably the most frequently reappearing, as well as the most popular, of Ultraman Leo's enemies, not surprising given his manipulative nature and formidable combat abilities.
  • Evil Knockoff: His main combat specialty and the general role in many of his appearances is to transform himself into an evil version of an Ultraman, such as Astra or Ultraman Hikari, in order to sow distrust between human and Ultras, or Ultras and each other.
  • Grappling-Hook Gun: Comes with the arm cannon on his left bracer, serving to ensnare foes.
  • Horned Humanoid: The two pointy horns sticking from his hair. According to one manga, they're the source of his shapeshifting powers.
  • Jerkass: Babalou is cruel, aggressive, arrogant, and manipulative. He delights in the distrust and prejudice he creates in his disguises, even going as far as to use Leo's feelings for his brother to deceive him into battling the Ultra Brothers.
  • Manipulative Bastard: In his debut series, he uses the disguise of Astra to trick Ultraman Leo into battling the Ultra Brothers and assists him in the process. If it wasn't for a timely reveal by Ultraman King, the Earth and the Land of Light would have both been destroyed.
  • Shapeshifter: Like Alien Zarab of the original Ultraman fame, he specializes in doing this. However, he's no wimp in combat once the heroes catch on to his disguise.
  • Spell My Name with an "S": Babalou or Babarue?

Commander Black

First Appearance: MAC Annihilated! The Flying Saucer is a Living Creature!
Played by: Takeshi Obayashi
A mysterious alien who commands monsters known as Flying Saucer Beastsnote  — a class of alien kaiju that can transform into flying saucers for space travel. Commander Black is the Big Bad for the final twelve episodes of the show, calling forth his minions from a sentient planet called the Black Star.
  • Beard of Evil: Sports a very villainous-looking goatee.
  • The Beastmaster: He's the commander of the Flying Saucer Beasts.
  • Big Bad: Becomes this with his arrival as the series didn't really have one previously.
  • Crystal Ball: He carries one that is used to call forth the Flying Saucer Beasts from the Black Star.
  • Establishing Character Moment: His debut has him wipe all of MAC out and kill an entire shopping mall full of people with Silver Bloom...while calmly walking through the panicked civilians before giving a Slasher Smile.
  • Evil Is Hammy: While we don't hear him speak very much early on, his habit dramatically announcing the names of the next Flying Saucer Beast would certainly qualify him for it.
  • Evil Wears Black: From the hat to the cape to the tip of his boots.
  • Genre Savvy: Whereas most Ultra Series aliens will see humans as too puny to be of any threat to them and end up defeated because of that assumption, Commander Black knows that a defense team can legitimately be a threat and takes MAC down before they can even know of his invasion plans.
  • Hero Killer: Kills all of MAC in his first appearance. He later temporarily kills Leo by hacking him to pieces.
  • Human Aliens: When his face is finally revealed, he looks very much like a human.
  • I'm Melting!: Dissolves into foam after being killed by Tooru and his friends.
  • Karmic Death: Repeatedly endangers the children Leo has befriended and uses one as a hostage for the Final Battle. Those kids proceed to beat him to death.
  • Knight of Cerebus: The series was already dark, this guy took it to a whole other level. To point: before his debut is over, he's already gotten a double digit body count.
  • Orcus on His Throne: Normally just commands his monsters from a distance and doesn't fight Leo himself. Justified, as while capable of jumping far distances, he's ultimately overwhelmed by children, so he wouldn't be much of a match for Leo. Subverted in the manga adaptation, where he grows giant to fight Leo himself.
  • Sadist: It's quite clear Black really enjoys what he's doing while murdering hundreds of people and slicing Leo to pieces.
  • Slasher Smile: Flashes many, both subtle and completely psychotic.
  • The Villain Knows Where You Live: He's aware of Leo's Secret Identity and makes very good use of that fact.
  • Would Hurt a Child: Repeatedly has his monsters target Leo's young friends to get at him. In Leo's battle with Black End during the finale, he threatens to kill Tooru in an attempt to demoralize the hero and let his monster win. It almost works.

Silver Bloome

First Appearance: MAC Annihilated! The Flying Saucer is a Living Creature!
The first of the Flying Saucer Beasts to be sent to Earth, showing off how much more lethal these monsters are compared to Leo's previous foes through a real whammy of an introductory rampage.
  • Big Eater: Eats the MAC space station!.
  • Combat Tentacles: Relies on these in battle, as well as to wrap around anything it desires to consume.
  • Flying Seafood Special: A gigantic jellyfish.
  • Knight of Cerebus: As the very first of the Flying Saucer Beasts, Silver Bloome shows how dark things are getting by killing all of MAC (except Gen), Momoko, Kaoru, and Takeshi within the first 6 minutes of the episode.
  • Poisonous Person: Silver Bloome can spew a highly flammable, toxic liquid from its mouth. However, rainwater seems to dilute this, as Leo's Battle in the Rain with the monster sees him and some kids get splashed by the stuff with no effect.
  • Sizeshifter: Makes itself tiny, which it does to hide from Ultraman Leo for most of the episode.
  • Swallowed Whole: Silve Bloome can consume nearly anything completely, increasing the size of its mouth as appropriate.
  • Voluntary Shapeshifting: Can transform itself into a rock shaped like a flying saucer. Tooru and his friends discover it and bring it to class, where Silver Bloome shifts into its small form and attacks their teacher later on.

Black Dome

First Appearance: The Flying Saucer Beast From an Evil Planet is Here!
The second Flying Saucer Beast to come to Earth. Black Dome causes trouble by injuring the family of one of Tooru's friends, Oba, when the kids accidentally attract its attention in an attempt to try make contact with alien spacecraft.
  • Flying Seafood Special: A crab.
  • Giant Enemy Crab: Based on horseshoe crabs and fiddler crabs to be exact.
  • Hollywood Acid: Its primary ability is to spit acid foam capable of turning apartments into mush within minutes.
  • Right Hand of Doom: Like a fiddler crab, Black Dome's left pincer is far larger and stronger than its right one.
  • Sizeshifter: It makes itself tiny to hide for most of the episode.
  • Super Spit: Black Dome's acid foam comes from its mouth in imitation of the foaming that real crabs do to help with breathing on land.


First Appearance: Leo is in Danger! The Assassin is a Flying Saucer Beast!
The third Flying Saucer Beast summoned by Commander Black. Absorba hides from Gen between rampages by shrinking itself and letting itself be taken under the care of a lonely boy named Hideyuki who loves animals and tends to them.
  • Combat Tentacles: They are mainly used to fire energy blasts or shoot fire instead.
  • Flying Seafood Special: Another gigantic jellyfish, just like Silver Bloome.
  • Manipulative Bastard: Takes advantage of a boy's love for animals to be sheltered in a small shed when not rampaging.
  • Meaningful Name: Absorba absorbs oil to gain its fire powers.
  • Playing with Fire: Can use the suction cups at the tips of its tentacles to act like flamethrowers.

First Appearance: The Red Assassin That Beckons Death!
The tenth Flying Saucer Beast that Commander Black summons. Nova disguised itself as a red Teru Teru Bozu, letting itself be discovered by Tooru before taking control of him to create illusions of his deceased family for him and spraying insanity gas at all who approached.

Noted as one of the most bizarre kaiju ever made for the Ultra Series, Nova has made several other appearances in the franchise. Nova is one of the very few Ultraman Leo kaiju (rather than seijin) that the producers have ever brought back with notable reappearances including Ultraman Mebius and Ultraman Orb.

  • Beware the Silly Ones: Yes, it looks silly, but Nova is a very dangerous monster and among the most powerful Flying Saucer Beasts.
  • Breakout Villain: Along with Alien Magma and Alien Babalou, Nova is considered one of the "mascot monsters" of Ultraman Leo. Its sheer weirdness probably helps with the memorability.
  • Breath Weapon: Asides from the insanity gas, Nova can shoot fireballs from its mouth. These fireballs split into smaller ones upon impact to generate a series of explosions.
  • Combat Tentacles / Whip It Good: Nova's right hand is a cluster of whip-like tentacles that are able to stretch out to impressive lengths.
  • Eye Beams: Able to fire a pair of blue lasers from its eyes.
  • Hate Plague: Nova's signature ability is its deadly "Red Crazy Gas", that cause humans to turn violently insane. Against Ultras it functions more as a smokescreen.
  • Mind Control: What it does Tooru, by latching itself onto his shoulder, causing him to see illusions of his deceased family beckoning him.
  • Our Monsters Are Weird: Giant, red Teru Teru Bozu that breathes insanity gas and turns into a flying saucer...You gotta wonder where the monster designers come up with these ideas sometimes.
  • Red Is Violent: Asides from being a very dangerous kaiju, there's also the red insanity gas.
  • Sinister Scythe: Nova's left hand is a giant sickle.
  • Sizeshifter: Can turn itself into a smaller form that can be mistake for a Teru Teru Bozu. The illusion goes away once the little guy starts spraying insanity gas at people though.
  • Spin Attack: Nova transforms into flying saucer mode by spinning its body about into a disc-like shape. In flying saucer form, Nova is able to slam into foes at high speeds.
  • Teru Teru Bozu: Nova's inspiration. Goes to show you can make anything into a kaiju.

Alien Bunyo

First Appearance: Leo's Life! The King's Miracle!
Voiced by: Keizo Kanie (also human form actor)
An alien mercenary hired by Commander Black when he was down to his last Flying Saucer Beast. Although Commander Black was initially unimpressed by the alien's goofy mannerisms, Bunyo had a foolproof plan to defeat Ultraman Leo, soon proving himself to be one of the hero's most deadly foes.
  • Ax-Crazy: Made most clear when he kidnaps Ms. Miyama while cackling manically, warning Gen and Tooru not to call the police or he'll kill her. The there's when he and Commander Black hack Ultraman Leo to pieces with a saw.
  • Beware the Silly Ones: Bunyo proved to be one of Ultraman Leo's most formidable enemies despite his silly behavior and design. Even Commander Black was impressed.
  • Breath Weapon: Asides from his slime, he also spits showers of explosive sparks.
  • Faux Affably Evil: Sure, Bunyo acts friendly and silly, but if you don't watch your back, you're probably not going to live much longer.
  • Hero Killer: He and Commander Black manage to capture Gen and chop Ultraman Leo into pieces! Fortunately, Ultraman King showed up at the last minute to save Leo.
  • I'm Melting!: He dissolves into a puddle of slime upon death.
  • Little Green Men: His normal form, complete with antennae.
  • Off with His Head!: Ultraman Leo defeats him by kicking his head off his shoulders with a well-placed Leo Kick.
  • Overly Long Tongue: Used to try strangle Leo.
  • Psycho for Hire: Commander Black brought him in to kill Ultraman Leo after Black End was all he had left.
  • Super Spit: Spits nasty green slime in combat that even Leo can slip over. He also excretes a similar substance from his body for protection.

Black End

First Appearance: Goodbye, Leo! Journey to the Sun!
The last and mightiest of the Flying Saucer Beasts to be summoned to Earth. Commander Black wanted the dragon-like beast to defeat Ultraman Leo above all else, while the Black Star followed close behind...
  • Armless Biped: Presumably, Black End's tail serves as balance.
  • Beware My Stinger Tail: Its tail has a pincer that can be used to grab foes.
  • Breath Weapon: A stream of fire.
  • Cephalothorax: Black Head is pretty much a little head on a big body with legs and a tail.

  • Our Dragons Are Different: Black End is designed to be something akin to a dragon.
  • Spikes of Doom: Black End has a number of these that can pop out of the black spots on its body whenever needed. They're also able to rotate.
